“They were the top two today in the practice order,” SDSU offensive coordinator Andy Ludwig said Friday. “I’m going to evaluate the tape real close. Every day we’re trying to evaluate tape and trying to make judgments and not trying to drag this thing out and make this a four-horse race or three-horse race for very long. We’ve got to give the guys quality reps. If you spread them too thin, nobody is going to get better, and nobody wins.”

Friday’s practice was the third of 15 spring practices and the first in full pads. In the first two spring practices, four quarterbacks got roughly equal snaps in their bid to replace departed four-year starter Ryan Lindley -- Dingwell, Katz, junior Jake Bernards and redshirt freshman Chad Jeffries.

A fifth QB – true freshman Matt Morin – only received limited snaps because coaches said he will redshirt this year.

On Friday, Dingwell and Katz got most of the work with the full offense, with Jeffries getting some occasional snaps.

Asked if he considered Katz and Dingwell better than the others, Ludwig said it was “too early to say that.”

"We’re still working with a practice order more than we are a depth chart," Ludwig said. "We're trying to let the position separate itself."

Bernards and Jeffries still could roll into the regular rotation, according to the film evaluation.

Injury update: Redshirt freshman receiver Paul Pitts might be out for the 2012 season with a ligament tear in his left knee, head coach Rocky Long said. Pitts played in the season opener last year but missed most of the rest of the year with an ankle injury. The good news for Pitts is that he might qualify for a sixth year of eligibility and be able to play four more seasons after this one. He tore the ligament in Tuesday's practice.

Practice update: How did Long view the first spring practice in pads?

“I thought they were enthusiastic, and I didn’t think anybody looked like they were afraid to run into each other, and that’s a good sign,” Long said. “That’s a little different than it was around here a couple of years ago. They didn’t want to run into each other. Now they want to run each other. They’re not doing it the right way yet, but you’ve got to have the will before you learn how, right?”

Spring practice resumes Tuesday.

Rule changes: Among the new NCAA football rule changes announced Friday, one is a new rule prohibiting players from leaping over blockers in an attempt to block a punt.

“I think they’re legislating football out of football,” Long said.

Kickoffs also were moved from the 30-yard line to the 35, which will lead to more touchbacks and fewer returns. Additionally, players who lose their helmets on a play now must leave the game for at least the next play. The idea behind the changes is to increase player safety.
